2.3 20v electrical issues..

Hi guys, Just bought a 2.3 20v (7a code) with some electrical issues. I have repaired the idle control valve and throttle sensor, but now seem to have a coolant temp sensor problem. The replacement sensor had 2 pins not the 3 as the original had. What is the third pin for? Only 1 of the 4 pins on the coolant temp sensor loom seems to go back to the ECU...

Does anybody know where I can get the wiring diagrams for this engine? I could do with working out which pins on the ECU go to which sensors.

This is starting to really stress me out now!

Cheers!

The ECU temp sender is the 2 pin white/brass one on the back of the head
